i965/fs: add support for shader float control to remove_extra_rounding_modes()
The remove_extra_rounding_modes() optimization will remove duplicated rounding mode changes. v2: - Fix bug in the rounding mode change (Alejandro). v3: - Fix rounding modes. v4: - Updated to renamed shader info member and enum values (Andres). v5: - Simplify flags logic operations (Caio).
